Description

Technical Field

[0001] The present invention relates to the technical field of drift inwards-opening windows, and particularly to a structure of a drift inwards-opening window pulley frame assembly provided with a hook. Background Art

[0002] Drift inwards-opening windows generally adopt an imported track design, with smoother pushing and pulling, multiple internal fulcrums, and strong wind resistance. It overcomes the disadvantages of poor sealing of sliding windows, easy damage of accessories, and occupied space and falling fans of casement windows. However, during the use of existing drift inwards-opening windows, when the window sash is not fully opened, the window sash does not completely disengage from the window frame. At this time, the window can be pulled, causing the lock points on the window sash and the window frame to collide, posing a certain safety hazard. Therefore, we propose a structure of a drift inwards-opening window pulley assembly provided with a hook. Summary of the Invention

[0003] The purpose of the present invention is to solve the deficiencies in the prior art and propose a structure of a drift inwards-opening window pulley assembly provided with a hook.

[0004] To achieve the above purpose, the present invention adopts the following technical solutions:

[0005] A structure of a drift inwards-opening window pulley frame assembly provided with a hook, comprising a pulley frame, a swing arm, a support plate, a dialing pin, a hook, and a positioning block. The lower end of the pulley frame is open, and openings are provided at both ends of the pulley frame. Two corresponding pulleys are rotatably installed at the lower end inside the cavity of the pulley frame. The middle part of the upper end of the pulley frame is rotatably hinged to the swing arm through a hinge shaft a. The hook is installed at the rear end inside the cavity of the pulley frame through a hinge shaft b, and the hook extends out of the pulley frame through the end opening. The dialing pin is located at the upper end inside the cavity of the pulley frame, and the dialing pin can slide back and forth along the inside of the cavity of the pulley frame. A dialing cylinder is fixedly provided in the middle of the dialing pin. A long hole is opened at the upper end of the pulley frame, and the dialing cylinder passes through the long hole and is inserted into a dialing groove at the bottom of the swing arm. The dialing groove is an eccentric groove around the hinge shaft a.

[0006] Preferably, it further includes a support plate. The swing arm and the support plate are rotatably hinged through a hinge shaft, and the support plate supports the weight of the window sash.

[0007] Preferably, two sets of closing dialing edges and one set of opening dialing edges are provided at the rear end of the dialing pin, and two sets of closing dialing edges and one set of opening dialing edges are provided at the top of the hook.

[0008] Preferably, two corresponding round holes are further provided at the upper end of the pulley frame. The dialing pin is located inside the cavity of the pulley frame, and two corresponding long holes are opened on the dialing pin. A rivet is connected between the long hole and the round hole. The diameter of the rivet is smaller than the width of the long hole, which can ensure that the dialing pin can slide back and forth inside the cavity of the pulley frame.

[0009] During the use of this device,

[0010] After the pulley frame moves backward and contacts the positioning block, it cannot move further. The force of closing the window forces the swing arm to rotate counterclockwise, and the inner wall of the toggle groove pushes the toggle cylinder, thereby driving the toggle needle to move backward. The toggle needle pushes the hook to hook the positioning block, and the pulley frame is fixed. When opening the window, the window opening force pulls the swing arm to rotate clockwise, and the toggle needle pulls the hook to rotate counterclockwise, separating from the positioning block, and the pulley frame can slide forward.

[0011] The beneficial effect of the present invention is that if the swing arm has not been fully opened during the window opening operation, the hook is always hooked with the positioning block, and the pulley frame cannot slide forward, thereby avoiding collision between the window sash and the hardware on the window frame. The person operating the window opening can only apply force in the direction of continuing to open the swing arm until the swing arm is fully opened and the window sash is completely separated from the window frame, and then the pulley can be pulled to slide, thereby avoiding collision between the window sash and the hardware on the window frame and improving the safety of the device.

DETAILED DESCRIPTION

[0025] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0026] Reference Figures 1-12A drifting tilt window pulley assembly structure provided with a hook comprises a pulley frame 1, a swing arm 2, a support plate 3, a toggle needle 4, a hook 5 and a positioning block 6. The lower end of the pulley frame 1 is open, and openings 15 are provided at both ends of the pulley frame 1. Two corresponding pulleys 16 are rotatably installed at the lower end of the cavity of the pulley frame 1. A hinge shaft a11 for connecting the swing arm 2 is provided in the middle of the upper end of the pulley frame 1. A hinge shaft b12 adapted to the hook 5 is provided at the rear end of the pulley frame 1. Two corresponding circular holes 14 are also provided at the upper end of the pulley frame 1. The toggle needle 4 is located at the upper end of the cavity of the pulley frame 1. Two corresponding long strip holes 41 are provided on the toggle needle 4. A rivet with a brim is connected between the long strip hole 41 and the round hole 14. The diameter of the rivet is smaller than the width of the long hole 41, and the brim of the rivet is larger than the width of the long hole 41. The toggle pin 4 can slide along the rivet in the cavity of the pulley frame 1. The upper end of the toggle pin 4 is fixedly provided with a toggle cylinder 42. The upper end of the pulley frame 1 is provided with a long hole 13. One end of the swing arm 2 is rotatably hinged with the pulley frame through a hinge shaft a11. The bottom surface of the swing arm 2 is eccentrically provided with an arc-shaped toggle groove 21 with the rotating hinge shaft a11 as the center of the circle. The toggle cylinder 42 passes through the long hole 13 and is inserted into the bottom of the swing arm 2. On the inner side of the arc-shaped toggle groove 21, the two ends of the pulley frame 1 are also provided with end openings 15, the hook 5 passes through the end opening 15 and extends out of the pulley frame 1, and the hook 5 is provided with a rotating hinge hole c51 adapted to the hinge shaft b12, the rear end of the toggle needle 4 is provided with a closing toggle edge line a43 and an opening toggle edge line a44, and the rear end of the hook 5 is provided with a closing toggle edge line b52 and an opening toggle edge line b53. When the toggle needle 4 moves backward, the closing toggle edge line a43 pushes the closing toggle edge line b52 The hook 5 is forced to rotate clockwise, and the hook 5 turns downward to hook the positioning block 6. A hook hooking surface c54 is provided below the front end of the hook 5, and a positioning block hooking surface c61 matched with the hook hooking surface c54 is provided above the rear end of the positioning block 6. When the dial needle 4 moves forward, the opening dial edge line a44 pulls the opening dial edge line b53, forcing the hook 5 to rotate counterclockwise, thereby separating the hook 5 and the positioning block 6. A mounting hole is also provided on the positioning block 6, and the mounting hole facilitates the positioning block 6 to be fixedly connected to the window frame.

[0027] Furthermore, a support plate rotation hinge hole 31 is provided at the upper end of the support plate 3, and the support plate rotation hinge hole 31 is rotationally hinged with the rotation hinge hole b23.

[0028] Furthermore, a joint 17 is provided at the front section of the pulley frame.

[0029] Furthermore, the front end of the dial pin 4 is provided with two groups of closing dial edges a43 and one group of opening dial edges a44, and the rear end of the hook 5 is provided with two groups of closing dial edges b52 and one group of opening dial edges b53.

[0030] Furthermore, when the pulley frame 1 contacts the positioning block 6, the swing arm 2 is rotated counterclockwise so that the toggle cylinder 42 is at the end of one end of the arc-shaped toggle groove 21, the closing toggle edge line a43 contacts the closing toggle edge line b52, and the positioning block hooking surface c61 contacts the hooking surface c54; the swing arm 2 is rotated clockwise so that the toggle cylinder 42 is at the end of the other end of the arc-shaped toggle groove 21, the opening toggle edge line a44 contacts the opening toggle edge line b53, and the positioning block hooking surface c61 is separated from the hooking surface c54.

[0031] In this embodiment, during the use of the device, when the window is closed, pushing the window sash is equivalent to pushing the pulley frame 1. When the pulley frame 1 contacts the positioning block 6, the pulley frame no longer continues to move backward. The window closing force forces the swing arm 2 to rotate counterclockwise, so that the toggle cylinder 42 reaches the end of one end of the arc-shaped toggle groove 21, and the toggle needle 4 moves backward. The closing toggle edge line a43 contacts the closing toggle edge line b52, the positioning block hook surface c61 contacts the hook hook surface c54, and the hook 5 is connected to the positioning block 6. Frame 1 is temporarily fixed; when the window is opened, when the window opening force pulls to the left, the pulley frame cannot move because the hook 5 is hooked with the positioning block 6, and the window opening force can only force the swing arm 2 to rotate clockwise, and the toggle groove 21 makes the toggle cylinder 42 slide forward along the long hole 13, and the toggle needle 4 moves forward, and the opening toggle edge line a44 contacts the opening toggle edge line b53, and the positioning block hooking surface c61 is separated from the hook hooking surface c54. At this time, the hook 5 is separated from the positioning block 6, and the pulley frame can slide along the guide rail.

[0032] When the swing arm 2 is not completely rotated, the hook surface c54 of the hook is still connected to the hook surface c61 of the positioning block, and the pulley frame 1 cannot move, thereby improving the safety of the device.

[0033] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
